MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The document contains a lure for game cheats and free spins, directly requesting users to click a link to download a file. The heuristic 'SE_SECRET_RECOVERY_LURE' indicates the document may attempt to phish for sensitive information like private keys or passwords under the guise of game account recovery. The presence of multiple embedded URLs pointing to similar download sites reinforces the malicious intent.

  • Nyx PDF Classifier malicious score 0.9769

Heuristics 4

  • Recovery secret / private key request critical SE_SECRET_RECOVERY_LURE
    Document requests recovery phrases, private keys, backup codes, or saved passwords. Requests for these secrets in a document are high-risk.
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
